SPECIFICATION forming part of Letters Patent N 0. 700,254, dated May20, 1902.

Application filed May 27, 1901. Renewed March 17, 1902. Serial Nd- 98A57- (No model.

To all whom, it may concern:

Be it known that I, CHARLES G. STEUBLER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Scales, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to scales, and has more particular reference to the construction of bearings for the various pivotal points.

It is the object of the invention to provide means for retaining the bearing-blocks in position so that they will be free to have a limited oscillating movement to adjust themselves to the knife-edge pivots.

The invention consists in the peculiar construction of a retainer for the bearing; further, in the particular construction of bearings for the various parts of the scale, and, further,in the peculiar construction, arrangement-,and combination of parts,as hereinafter described and claimed.

In the drawings, Figure 1 illustrates diagrammatically one of the platform-levers, the steelyard-rod, and platform and shows in section the bearings for said steelyard-rod, platform, and supporting-loop for the platformlever. Fig. 2 is a perspective view of a bearing-block and retainer detached. Fig. is a longitudinal section on line 03 m, Fig. 1, and showing a modified construction from that shown in Fig. 2. Fig. 4: is a perspective view of the casing shown in Fig. 3.

A is asteelyard-rod B, one of the platformlevers; G,the platform, having depending feet D, and E is a bearing-loop for supporting the platform-lever. These parts may be of any desired construction and form no part of the present invention except as hereinafter set forth.

F, G, and H are respectively the bearings for the lower end of the steelyard-rod, the platform-bearing,andthe supporting-loop for the platformdever. Each comprises a bearing-block (1,, preferably formed of agate or other hard substance, which is inclosed by a metallic casing 12. The latter is preferably formed of sheet metal bent to embrace three sides of the block and having inwardly-turned flanges c for engaging with the edges of the fourth or hearing side of the block. The

block may be engaged with the casin g by slidingit in. from the end and is thenheld from disengagement by a pin or bar I, which forms the opposite bearing for the block. This pin or bar is adapted to engage-with-a transverse groove d, formed in one side ofthe block, and passes through registering apertn res e,formed in the sides of the casing, thus locking the block and casing in fixed relation.

In the construction shown for the bearing H the casing 19 is cut away in the bottom opposite the transverse groove din the block, so that the two parts may be engaged with the bar I, which in this bearing forms an integral part of the supporting-loop J. bearing G the casing his provided with an "imperforate upper side f, and the pin I is engaged with the block and "easing by an endwise movement. This pin also passes through registering apertures in the furcations g, formed at the lower end of the feet D of the platform. When the parts are engaged, the casing will form a retainer for holding the block in position when the platform is lifted, and this is for the reason that the imperforate upper side f of the casing passes above the pin I and forms a hanger for the block.

In the bearing F the casing b and block a may be of similar construction to that of the bearing G, while the pin I secures said block and casing to the hooked lower end K of the steelyard-rod. This hook is preferably formed by bending the lower end of the rod A to form a lateral offset and then by bending to form an inverted U which embraces the three sides of the casing b and centers the block in line with the upper portion of the rod A.

With all of the bearings F, G, and H the metallic casing and bearing-block are held from longitudinal displacement in relation to each other by a pin or bar I. In order to prevent danger of any binding between the metallic casing and the pin, theformerlhas ';the

In the slot 6 therein sufficiently enlarged so-that the bearing of the pin will be uponthe blockalone and not upon the casing. Thisf will prevent ICO for the bearing-block in addition to its function in securing said block in position is to prevent the breaking or chipping of the upper edges of the block. As the bearing-blocks 'are usually made of agate or other hard brittle gaged therewith by an endwise movement and a support for said block having a pin or bar extending transversely of and bearing upon said block and adapted to hold said casing and block from endwise displacement in relation to each other.

2. A scale-bearing comprising a transversely-grooved bearing-block, a casing embracing said block and adapted to be in en gagement therewith by an endWise movement, said casinghaving apertn res in its sides adapted to register with said groove in the block, and a support embracing said casing and block having a transverse bar or pin for engaging said transverse groove, said bar or pin forming a pivotal bearing for said block.

A scale-bearing comprising a transversely-grooved bearing-block, a casing embracing said bearing-block by an endwise movement and having apertures in its sides for registering with said groove, and an imperforate portion opposite the side of said groove; a bifurcated support for embracing the sides of said block and casing and a pin passing through said support and groove in said block whereby the latter has a pivotal bearing on said pin and whereby said casing r is held from endwise movement and forms a retainer for preventing disengagement of said block from said support.

4. A scale-bearing comprising a bifurcated support, an incased bearing-block embraced by said support and a transverse pin or bar in said support forming a pivotal bearing for said block; said block being provided with a transverse groove for engaging with said pin and the casing for said block having apertures in its sides registering with said grooves but extending inward beyond the bottom of said groove whereby said pin will have its supporting-bearing upon the block only and will hold said casing from endwise movement.

5. In a scale a steelyard rod having a hooked lower end, a bearing-block and a casing therefor, the latter fitting Within said hook and a pin for pivotally connecting said casing to said hook adapted to lock said block in engagement with said casing.

In testimony whereof I affix my signature in presence of two Witnesses.
